Day By Day: iAchieve lets you mark off specific tasks with icons like smiley faces; you can also add daily text notes, which are marked with a dot in the calendar view.

The app aims to let you track any daily activities—like going smoke-free, remembering to exercise, or taking your vitamins. You can set up as many users as you’d like to track within iAchieve, and each user can set an unlimited number achievements to track. Parents might find that the app is useful for charting their kids’ chores or successes, but frankly, my own 2-and-a-half-year-old prefers the magnetic chart in the kitchen to this digital counterpart.

If you or your family are into daily achievement tracking, though, iAchieve sports some endearing options. You can choose from a variety of built-in icons to mark each day you want to mark as a success, like happy faces, stars, or checkmarks. You can set the background color for each achievement you track, too. iAchieve lets you save a daily text note as well, which you can recall from the calendar view.

iAchieve could take one cue from Wii Fit , Nintendo’s fitness tracker for its Wii game console. I’d prefer that iAchieve let you more easily use a new icon for different days instead of requiring a series of taps through different settings screen to change it.

For tracking daily tasks, iAchieve simply works. The app doesn’t offer many bells and whistles, but it certainly gets the job done.

iAchieve is compatible with any iPhone or iPod touch running the iPhone 2.x software update.
